I have noticed several times that people talk about being able to put up
a full .250 wavelength vertical and I have wondered why almost never do they
think about making it .270 wavelength instead of .250 wavelength

Pat,
My Inverted L is longer than a quarter wavelength. I also use it on the HF
bands 80-20 and it is easier to match since it is not a multiple of a half
wavelength

What do you mean by linear loading?
How long are your radials?

I have noticed several times that people talk about being able to put up

they think about making it .270 wavelength instead of .250 wavelength. The
little extra length gives a feed point impedance of 52 ohms with some

One solution might be top hat vertical, similar with
http://dl2kq.de/ant/3-1.htm . Not sure how much power is lost in the
matching unit L1, C1.
I would love a Waller Flag too. Imposible to buy one from here
Check out DX Engineering. They sell a vertical that uses 3 top hat
wires. Sloping back down is ok. For 80/160 you need to stop the 80m
energy with a coil/trap My 80 uses a very fast taper and the top is
only 3/8 inch or less so It cannot support a coil or t wires. I
probably should have
I can try to put a 21-22m (68-70 foot) telescopic aluminium pole, made from
pipes 2" to 1" diameter.
It will be a bit too long for 1/4 on 80m. I can put a T top hat or run an
InvL, but probably need to slope it from 70 foot to about 40 foot. What
will be better ? and will I be able to match/use
160 and 80 will be difficult. Can you get another vertical up about 60
feet? You can top load that with a trap for 80 and have "t" wires at
the top that also act as guy wires.You can also bottom load for 160
and maybe that will be good enough for you. Radials whatever you can do
will
Hi,
I got my first ham license 2 years ago, and because I couldn't install an
antenna at home, I've worked mostly portable (SOTA, WWFF activations).
In February 2016 participated on CQ 160 SSB from YR8E and got the
"contesting virus". So, I've started to built a QTH at my parents home,
